Application filed November 10, 1919. Serial No. 336,790.

To all whom it may concer Ee it known that l, PAUL (il. Boonen/wr, a citizen oi the United States, residing at Battle lFreek. in the county otI Calhoun and State of lvlichigan.y have .invented certain new and useful Improvements in Split Lubricating Bearings for Shai'ts, etc.; and l hereby declare that the following is i'ull, clear. and exact description thereof, reference beingl had to the accompanying drawings. which t'orin part ot `this specifloat-ion.

This invention is an improvement in selllubricating journal boxes or bearings Vfor shafts; and its object is to provide a novel journal box which may be mounted on. a pedestal` a brac iet, or a hanger; and to provide novel means whereby7 the bearing is self-lubricating; and v-hercb'v longil tudinal play ot the shaft in the bearing may be prevented and end thrust thereol' nullified.

I will explain the invention with reference to the accompanying drawings which illustrate a practical embodiment there/it. and will enable others skilled in the art to manu* 'facture and use the same; and in the claims I have set torth the essentials ci the invention and the novel 'features oi construction and novel combinations of parts for which protection is desired.

.ln said drawings:

l is a longitudinal sectional elevation ot the journal box on the line ot the shaft, such journal box being shown as supported on a pedestal.

Fig. 2 is a vertical section on the line 2, Fig. l.

Fig. 3 is a partial top plan view and part section on the line 3 3 of Fig. 2.

Fig. e is a top plan view oit the cover detached.

VFig. 5 is a sectional view oi the cover on the line 5-5, Fig. il.

Fig. 6 is a longitudinal Section ol" one oi" the journal boxes mounted in a bracket.

.F ig. 7 is a transverse section on the line 1 -7, Fig. (l.

Fig. 8 is a transverse section of a journal box suspended in a hanger.

Fig, 9 is a side View of Fig. S.

The journal box as shown is divided hori- Zontally on the axial line of the shalt and the bearing surfaces are divided both longitudinally and transversely thus forming two upper and two lower sections or a fourpart bearing proper.

As shown the casing ot the journal box consists ot' a lower portion l. which may be cast, it' desired, integrally with the stand? ard or support upon which the journal box is mounted, as in Figs. Vl. and Q; or it may be cast integral with a bracket support, as in Figs. 6 and 7; or integral with a base which is attachable to the support or hanger in which the journal boi; is to be mounted, as in Figs. 8 and 9. In each instance the part l remains substantially the saine. This part l is hollow and is provided with transverse bridge portions or arches i, lb, which support the two lower sections 2f* and 2b of the bushing in which the shaft S is journaled. The space or chamber O in the part l at the outer ends o1 and below the bridge members i, lb, forms an oil chamber which is adapted to contain a lubricant.

Each bushing section 2, 2b is concaved on its upper side to fit the shaft S; and each is provided with an exterior rib 2X adapted to engage a corresponding` slot X in its support, la or i, to prevent the bushing section turning in such support. Each bushing section is also preferablj7 provided ai' its inner end with flanges 2e, which flanges contact with opposite sides of a collar 3. which may be :fastened to the shaft by a screw 3a, or secured thereon by other suitable means.

`Fitted to and over the lower part l. ot the casing is a part l, which is also provided with transverse bridges or arches Lli, ab, corresponding in position with and respectively opposed to, bridges or arches la, lb of the part i. The part i maj,Y be secured to part l by bolts is, and the parts i and l have registering recesses in their ends for the passage of the shalt. An opening is preferablj7 formed in the upper side of the part as indicated in the drawing, such opening being surrounded by a flange LL, which is closed b v a coverI 6.

Fitted to the inner surfaces ol. the arches el. are bushing sections il* li. which correspond to the bushing sections Q, 2C, and therewith 'form complete bushings around the shaft S. The bushing sections lh. li may be provided with ribs ly, similar tothe ribs 2*, engaging slots LX in the arches ein, Lib. The bushing sections l, l are also provided on their inner ends with annular llO flanges 4e which bear against opposite sides The upper sections l, 1i of the bushingl preferably have their flanges 4e centrally thickened, as at 4f, on their outer faces, and engage corresponding slots or notches in the adjacent edges of the arches 4, 4", as shown, which will facilitate 'properly assembling and positioningthe bushing sections inthe bearing and preferably the upper thickened parts of the flanges are tapered or beveled downwardly away from the upper part of the collar 3, as indicated in the drawing; and preferably also the upper surfaces of the arches 4, 4b, (which extend across the opening in part 4) are also tapered or inclined away from the collar 3, as shown, and as indicated at 4i, (Figs. l and 6), so as to direct any oil or lubricant which may be introduced into the opening or raised into this opening by the collar 3 (or a ring or chain on said collar) to oil holes 4 located at the lowest part of the inclines 4i. The oil holes 4 communicate with holes ln in the bushing sections l, l; and the holes l may communicate with curved channels l in the bushing sections l, il, (as indicated in Fig. 6) soY as to distribute the lubricant thoroughly onto the shaft within the bushing.

-The collar 3 preferably has an annular groove 3 in its exterior, the sides of suoli groove being beveled outwardly as shown. and hung upon this collar is a ring 5, of larger diameter than the collar, whnh de-V pends into the lubricant chamber O in the part l, and is adapted to carry the. lubricant up on the collar into the opening in part 4, .where it overflows and is directed to the openings 4, and passes to the bearings. .any suitable devices for raising the lubricant may be employed; in Fig. 6 and Fig. T, I have'shown a chain 5x instead of a ring. lf the shaft is rotated rapidly oil picked up by thev ring will be thrown off, by centrifugal action, against the inside of the cover 6. This cover 6 is preferably pro vided with a depending flange 6 on its un` der side, which flange is cuived longtudinally as indicated in Fig. 4, and it is also narrow at its center and wider or deeper at its ends, as indicated in Figs. il and (i, so that any oil caught on this flange would naturally run by gravity down the inclined `lower edge of the flange to opposite ends thereof and drop from suoli ends into the holes 4"; the ends of the flange being preferably arranged to terminate just above said integrally holes 4. The `cover 6 should be madeto fit the flange 4 and close `the opening in the part 4; and be suitably fastened thereto. As shown the cover may be provided with ears 6b secured by a pin 6 to an ear 4 on the part4.

The collar 3 is designed to act both as a thrust collar and oil thrower. The ring or chain on the collar picks up the oil in the chamber 0. Part of this oil is thrown from the chamber in the direction of rotation and against the upper side of the cover in the flange 6a Vand such oil is directed to the holes 4. Pai-tof the oil will overflow the groove in the collar at the top thereof and pass down the inclined walls 4i to theholes 4,

thence the oil passes around the shaft.V

through the bearing and escapes back Vinto the oil chamber.

lf the bearing was used with a very slow running shaft the flange 6a in the cover would not be necessary, but for fast running shafts this flange is very important.

` The outer ends of the bushing Ymembers are preferably spared from the outer end walls of the parts l and 4, as shown, so that any lubricant which may be eXuded from the outer ends of the bearing may easily pass back into the lubricant chamber 0. I

The particular means of supporting the bearing may be varied according to the use or position in which the bearing is to be employed. For instance the'bearing can be mounted on a standard, as shown in Figs. l and 2; or on a bracket as shown in Figs. 6 and 7 or on a hanger, as shown in Figs. 8 and 9, yby simply properly modifying the form'of the lower part of the casing l. This casingy may be formed separately from its support or cast therewith, as desired; YAs shown in Figs. l and 2 the part l isV cast with a standard 7, which may be of any desired construction or forni. ,As shown in Figs. G and 7 4the part l israst `integral with a bracket member 8 projecting from one end of thep'art l and pro- Vvided with a flange Sasuitably perforated for the passage of retaining bolts by which the bracket and bearing can befastened in position to a suitable support. As shown in Figs. 8 and 9, the part l maybe provided with a base l, which may be adjustably mounted in a U-shaped hanger 9 of any suitable construction; and the base l.s may be mounted on adjustableY wedges 9 in the hangerQ and may be secured in adjusted position'by means of bolts 9b..
